Microsoft recommends that you use the Microsoft.Identity.Web NuGet package when developing an ASP.NET Core protected API calling downstream web APIs. Finally, we use the base.SendAsync() method to resume the HTTP request flow. Now change it so CancellationToken's timeout > HttpClient.Timeout: Repeat the test. finding a session on database) is likely to take more time than calculating an HMACSHA256 to validate a token and parsing its contents.

To call Microsoft Graph, Microsoft.Identity.Web enables you to directly use the GraphServiceClient (exposed by the Microsoft Graph SDK) in the API actions. The general concept behind a token-based authentication system is simple. Thanks. Alternatively, if a developer wishes to write the authentication service themselves, there are a couple third-party libraries available to handle this scenario. Of course, the specific names are not important, but it is important that the route matches the one given to EnableTokenEndpoint. Authorization Filter. Spring Security builds on this support to provide additional benefits: Spring Security will automatically refresh expired tokens (if a refresh token is present) Thanks to the maintainers of this library, it is relatively simple to generate a bearer token. Call the AuthenticateAsync method to obtain authentication properties. In the Python sample, the code that calls Microsoft Graph is in app.py#L53-L62. Since we inherited from IAuthenticationTokenProvider interface so we need to implement following methods in this class. Server side scalability): there is no need to keep a session store, the token is a self-contained entity that conveys all the user information. There also exists a KeyCloakRestTemplate which injects the header automatically. The address for the post should be the token_endpoint URI and the body of the post should be x-www-form-urlencoded and include the following items: Here are the complete request and response from me testing the connect/token API: The access_token is the JWT and is nothing more than a base64-encoded string in three parts ([header].[body].[signature]). If you have noticed, we are using dummy users like "Username 1" with "password 1", so let's build this project and run.

Step 6 You can do so by including the bearer token's access_token value in the HTTP request body as 'Authorization: Bearer {access_token_value}'. Bearer token The token is a text string, included in the request header. An example of a bearer header is the SendGrid API, which I covered in a previous blog post.
